HPG-I

 

Product: HPG

Chemical Name: Hydroxypropyl guar

CAS Number: 39421-75-5

 

Applications

As a nonionic polymeric viscosifier derived from natural Guar bean, HPG-I is of suitable substitution level, good aqua-dissolvability / dispersibility, and high compatibility with anionic, cationic and nonionic surfactant. With its good electrolyte tolerance, viscosity stability and good shear dilutability, HPG-I can be used in fracture fluids and drilling mud in oil field industry.

Fracture fluids are for the purpose to improve drill productivity and made by mixing HPG-I with water, cross-linker, polymerizing agent, and proppant. The normal level of use in fracture fluids is 0.3-0.5% by weight.

HPG-I polymer can also be used in low-solids drilling fluids as a viscosifier and fluid-loss additive. It will develop viscosity in both water and brine.
